You can consider Airtime, Google Hangout and other video tools for this purpose, but we’re going to introduce Screenleap to you because it’s an online app that runs instantly without sign-ups or installations.

Share your screen on the Fly

Once access is allowed, a small control window will appear at the front of your screen. When this control appears, your screen share is already active, select if you want to share the entire screen or share only screen ‘inside rectangle’.

Conclusion

Ridiculously simple to use, this app makes for a great tool to share your screen and offers you control over what you want to share and don’t. Just be careful of what is running on the background when you have the sharing on, alright?
